Definitions
- the invention relates to a closing unit for a blow molding machine with a first and second mold carrier and a blow molding tool with two tool halves arranged on the closing unit, each tool half being releasably attached to one of the two mold carriers and having an upper mold part and a lower mold part, the two tool halves between an open state and a closed state can be moved back and forth in a first direction of movement, the lower mold part of each tool half with respect to the upper mold part of each tool half in a second direction of movement different from the first direction of movement between an open state and a closed state by means of at least one first and at least one second actuator is movable and the blow molding tool in the closed state of the two tool halves delimits a mold cavity with undercuts when the two lower mold parts are also in the closed state.
- the invention relates to the production of hollow bodies by means of blow molding, in particular the production of containers made of plastic, such as canisters or bottles, for example.
- an extruder with a Blow head is a tubular preform that is enclosed by the blow molding tool and expanded by means of a blow mandrel introduced by compressed air in such a way that the hollow body in question has the inner contour of the blow molding tool.
- the two tool halves can generally be moved against one another in the horizontal direction by means of a closing unit in order to open or close the blow molding tool.
- the structure of such a locking unit is disclosed, for example, in DE 102012 109 499 A1.
- the containers to be produced can have depressions on the lower and / or upper side, for example to form a curved container base or a grip area.
- the depressions represent an undercut compared to a lateral demolding of the container from the tool halves.
- two-part tool halves of a blow molding tool are known from the prior art, the lower bottom half of which can be lowered relative to an upper mold part of the tool half.
- the lower bottom half of each tool half is lowered separately via at least one hydraulic cylinder and then raised again for a new production cycle of a container.
- a first blow molding tool used in practice two hydraulic cylinders are attached to the side of the upper mold part on a frame of the tool half and connected to the bottom half on the output side via the piston rod.
- a hydraulic cylinder is on the frame of the tool half below the lower bottom half attached and connected on the output side via the piston rod to the underside of the bottom half.
- the disadvantage of the first blow molding tool is that two actuators are required per tool half and the overall width of the blow molding tool resulting from their arrangement can cause problems. In the case of the second blow molding tool, it is not possible to change the blow molding tool from the side.
- US Pat. No. 5,026,268 A discloses a blow molding system for the simultaneous blow molding of two plant pots, the edge areas of which are compression molded.
- Each tool half of the blow molding tool has a total of five molded parts.
- the two lower and upper mold parts of each mold half are rigidly connected to one another and in turn rigidly attached to a base of the respective mold half. This base is part of the blow molding tool and forms the frame of each of the two tool halves.
- a hydraulic cylinder is attached to this frame of the blow molding tool and is connected to the two lower mold parts via a piston rod.
- the firmly interconnected lower mold parts of each mold half are movable relative to a mold part lying between them in the direction of a guide rod connecting the mold parts.
- the intermediate molded part is movable relative to the two upper molded parts firmly connected to the base of each mold half in the direction of a further guide rod. This relative movement allows the edge area of the two planters to be molded.
- the invention is based on the object of developing an arrangement of clamping unit and blow molding tool in such a way that the actuators do not restrict the clamping area of the blow molding tool, at the same time reducing the costs for blow molding tools and simplifying changing the blow molding tool.
- the solution is based on the idea of arranging the actuators, such as, for example, hydraulic cylinders, not on the blow molding tool itself, as was previously the case, but on the clamping unit and designing it to be couplable with the lower part of the mold.
- actuators such as, for example, hydraulic cylinders
- the object is achieved in a closing unit of the type mentioned in that the at least one first actuator and the at least one second actuator are arranged on the closing unit and one of the two lower mold parts is detachable with an output of the at least one first actuator and the other of the two lower mold parts is releasably connected to an output of the at least one second actuator.
- the actuators become part of the closing unit of the blow molding machine and remain on the closing unit when they are changed.
- only one set of actuators is required. Due to the releasable connection between each actuator and one of the two lower mold parts, changing the blow molding tool is simplified. At the same time, the space required for the blow molding tools is reduced.
- the actuators can be positioned on the machine side in a space-optimized manner in a space that is not or only partially usable for the blow molding tool.
- the actuators are preferably arranged below the lower mold parts and releasably connected to the underside of the respective lower mold part.
- the at least one actuator is arranged below the lower mold part and can be detachably connected to the underside of the lower mold part, this can be done
- the at least one first actuator and the at least one second actuator are arranged on the closing unit so that they can move relative to one another in the first direction of movement.
- a preferred embodiment of the invention provides that the at least one first actuator moves synchronously with the first mold carrier and the at least one second actuator moves synchronously with the second Mold carrier moves.
- the at least one first actuator can be arranged directly on the first mold carrier and the at least one second actuator can be arranged directly on the second mold carrier.
- a fastening bracket for indirect fastening of the at least one first actuator and a fastening bracket for the second mold carrier can be attached to the first mold carrier be arranged indirect fastening of the at least one second actuator.
- a further embodiment of the invention provides that the at least one first actuator and the at least one second actuator are movably arranged on the clamping unit along at least one stationary longitudinal guide, a first coupling the movement of the first mold carrier on the at least one first Actuator and a second coupling that transmits the movement of the second mold carrier to the at least one second actuator.
- a coupling rod or a carrier element can be used as a coupling, for example.
- a stationary guide present on the closing unit can be used as the stationary longitudinal guide for the actuators, along which the first and second mold carriers are also displaceably guided.
- a separate stationary longitudinal guide is provided for the actuators.
- a defined interface for power transmission is created by means of the releasable connection between the actuator and the lower part of the mold.
- the releasable connection is designed as a coupling in an advantageous embodiment of the invention, which is used for the transmission of forces between the actuator and the lower mold part at least in the second Direction of movement, that is to say perpendicular to the horizontal closing and opening movement of the two tool halves.
- the coupling is preferably designed as a switchable, non-positive or positive coupling, for example as an electromagnetic coupling.
- the actuators are set up in such a way that they can move the lower mold part linearly to and fro in the second direction of movement between the open state and the closed state.
- the actuators can be designed as linear drives, in particular as fluid-operated working cylinders.
- the actuator is a crank mechanism that converts a rotary movement into an oscillating thrust movement in the second direction of movement.
- the second direction of movement of the lower mold parts is usually perpendicular to the first direction of movement for opening and closing the blow molding tool, but can also run at a different angle depending on the hollow body to be produced.
